Assembly
Refer to the illustrations and parts lists for correct
orientation and placement of parts.
Replace any O-rings, V-rings, seals, and gaskets on
parts that have been disassembled. Apply hydraulic
fluid or O-ring lubricant to all O-rings and all metal
surfaces which they must slide over. When installing an
O-ring which must slide over sharp surfaces, use a
rolling motion and be careful not to damage the O-ring.
Wherever the assembly results in metal-to-metal
contact, coat the surfaces with hydraulic fluid or O-ring
lubricant.
Tamper Unit
1. Assemble the O-ring (6), U-cup seals (4, 5), and rod
wiper (7) to the packing nut (3).
2. Install the ram (2) into the tamper body (1).
3. Thread and tighten the packing nut into the end of
the tamper body.
4. Install the shaft (8) into the center bore in the tamper
body, as shown.
5. Install the plug (11) into the valve body (10).
6. Install the O-ring (15) into the plug (14).
7. Slide the spool (9) into the valve body, as shown.
Set the stop (12), flanged end first, into the spool.
Install the spring (13) over the stop and secure with
the plug (14).
8. Install the O-rings (16, 17) into their appropriate
bores in the bottom of the valve body (10).
9. Set the valve body (10) on top of the tamper body
(1) and align the scribed marks that were made
during disassembly. Fasten the valve body with four
cap screws (18).
10. Install the adapters (24) into the ports on the top of
the valve body.
11. Install the tamper foot (21) onto the end of the ram.
Install the cap screw (23) with washer (22) and
tighten the cap screw securely.
Valve Components
1. Install the O-ring (51) into the groove in the spool
bore of the handle (45), as shown.
2. Install the end cap (48) into the handle, flanged side
first, on the side of the handle opposite the trigger.
Secure the end cap into position with a retaining
ring (50).
3. Set the spring (47) into the spool bore of the handle.

4. Align the control spool so that the 3 mm (0.125")
diameter indentation in the spool indicates the
appropriate hydraulic system designation (OC or
CC). Slide the control spool into the spool bore.
Install the flat washer (49) onto the control spool and
secure the spool components with a retaining ring
(50).
5. Install the trigger lever (37) onto the control spool,
and secure with the roll pin (41).
6. Install the cover plates (38) with cap screws (39) and
stop nuts (40).
7. Insert the sleeve (43) and install the trigger lock (44).
Install the adapters (30) into the end of the handle.
Valve Components—Cool Grip
1. Install O-ring (48) onto OC/CC spool (49). Insert
OC/CC spool into trigger spool (47). Install retaining
ring (52). Adjust OC/CC spool to desired setting.
2. Install O-ring (50) and backup ring (51) into valve
handle (33). Install O-ring (46) onto trigger spool
(47). Slide the trigger spool assembly into the handle
from the trigger mount side of the handle.
3. Install spring (45), washer (44), and retaining ring
(43). Install pins (40) and retaining clips (41). Check
trigger spool operation.
4. Hold grip halves (34, 35) against handle (33) and
fasten in place with screws (36, 37) and nuts (38).
Do not overtighten.
Tube
1. Refer to the parts illustration and the markings on
the pressure hose for appropriate hose connection.
Connect the hoses (29) to the adapters (30) on the
end of the handle. Slide the hoses through the tube.
Connect the hoses to the adapters (24) on the valve
body.
2. Fasten the tube to the valve body with four cap
screws.
3. Slip the handle assembly into the end of the tube
(25).
On newer models, fasten with two cap screws (32).
On older models, fasten with the cap screws (35),
countersink washers (34), double washers (33), and
nuts (36).
Torque the cap screws to 14.9 Nm (11 ft-lb).
4. Apply a thread sealant, such as Loctite
Threadlocker, to the threads of the cap screws.
Follow the manufacturer's instructions for curing.
Install both halves of the guard (31) and secure with
